Eliminating a ornamental grass
We have an green ornamnetal grass that has overgrown to the point it is starting to surround a Mimosa tree root ball. We dont want to harm the tree by attemting to dig it up and are worried that Round-up may harm it. We just trimmed it down to about 6 inches and have seen posts suggesting suffocating as an option. Has this worked for anyone or are there other ideas. Thank you.
